New Berlin's Trusted Commercial Deck Builder


Your outdoor space is part of your customer experience. A well-built commercial deck adds seating, improves curb appeal, and gives customers a reason to linger. A poorly built one creates liability issues, constant repair calls, and headaches you genuinely don't have time for.


Brew City Builders has been the trusted deck company for commercial properties across New Berlin and southeastern Wisconsin since 2003. We've built commercial outdoor spaces for establishments including The Harp and Wauwatiki Bar and Grill, and we bring that same level of planning and craftsmanship to every commercial project we take on, regardless of size.


Call (414) 453-1235 to talk about your New Berlin commercial deck project.

Start Planning Your Commercial Deck 

Commercial outdoor spaces come with a different set of demands than residential builds. The layout has to support real daily use, the materials have to hold up under heavy foot traffic, and every detail from railings to traffic flow has to be thought through before the first board goes down. 


Brew City Builders works with business owners and property managers to plan commercial deck projects the right way, whether you need outdoor seating, tenant access, a customer area, employee break space, or a safer replacement for an aging structure. We help you work through the design, materials, and finishing details so the finished space feels professional, purposeful, and built to last. Contact Brew City Builders today to start planning your commercial deck installation.

Commercial Deck Installation That Actually Works for Your Business


Here's the thing about commercial deck installation. It's not a bigger version of a backyard deck. It needs to work harder, hold up longer, and fit how your business actually operates day to day.


Before we design anything, we come to your New Berlin property and look at how the space gets used. How many customers do you need to seat? Where do staff need to move? Are there drainage concerns? What are the occupancy load requirements? These questions matter before a single board goes down.



From there, Amy creates a custom 3D design of your specific property. You see exactly how the finished deck looks, how the layout flows, and how materials fit your building before we start any work. No surprises, no discovering mid-build that something doesn't work the way you imagined.

Materials Built for Commercial Use


The materials that work fine on a residential backyard deck aren't always the right call for a commercial property. Commercial decks see more foot traffic, more wear, and more exposure than anything a homeowner puts in their backyard. We use materials built for exactly that kind of demand.

For commercial composite decking, we exclusively use Timbertech Advanced PVC. Here's why it works so well for New Berlin businesses.



  • 100% PVC with no wood fibers, so it won't rot, splinter, or absorb moisture
  • Handles heavy foot traffic day after day without breaking down
  • Available in 15 colors to match your building's exterior
  • Needs only occasional soap and water cleaning, no staining, no sealing, no sanding
  • Less maintenance means less downtime and fewer ongoing costs


For restaurants and bars specifically, that last point matters a lot. You can't close your patio for a weekend of sanding and restaining every few years. Timbertech Advanced PVC just needs a quick clean and it looks great again.

Framing That Holds Up Under Commercial Load


Customers see the deck surface. What determines how long it lasts and how safe it is under daily commercial use is what's underneath.

We frame every commercial deck with KDAT lumber, which stands for Kiln Dried After Treatment. Standard pressure treated framing is wet when it leaves the treatment facility. Over time it shrinks, warps, and twists as it dries out. On a commercial property with heavy use, that structural movement creates problems fast.

This isn't an upgrade you have to ask for. It's the standard we hold every commercial deck installation to.

Commercial Deck Repair in New Berlin

Not every commercial project is a new build. If your existing deck is showing wear, structural issues, or surface damage, we can assess it honestly and repair it properly.


Sometimes a targeted repair is the smart move. Sometimes a full replacement is the better long-term investment. We'll tell you which one makes more sense for your situation rather than automatically pushing you toward the more expensive option.


Common commercial deck repair work we handle:



  • Replacing warped, cracked, or damaged deck boards
  • Fixing structural framing issues including joists, beams, and ledger connections
  • Repairing or replacing railing systems that no longer meet code
  • Addressing drainage problems that cause standing water or surface deterioration
  • Upgrading older wood surfaces to Timbertech Advanced PVC for lower long-term maintenance


If your commercial deck has been patched together over the years and is starting to show it, we can get out there, look at what's actually wrong, and give you a straight answer about the best path forward.

Railing Systems for Commercial Properties


Railings on a commercial deck need to meet safety codes and hold up under constant use. We offer options built for exactly that.


  • Westbury aluminum railings are rust-proof, low maintenance, and available in multiple colors to fit your building's exterior. They meet all commercial code requirements while keeping an open, professional look that doesn't feel heavy or industrial.


  • Fortress steel railing systems offer superior strength with powder-coated finishes that resist fading and weathering under heavy use. Great for properties that want traditional styling with commercial-grade durability.


  • Dan's custom fabricated steel railings are built by hand for businesses that want a distinctive look. Decorative screens, geometric patterns, one-of-a-kind designs that set your New Berlin property apart from every other restaurant or bar on the block. His metalwork creates railings that become part of your brand identity.


All railing installations meet applicable safety and building code requirements for commercial properties in New Berlin and surrounding Waukesha County communities.
